Steps to reproduce the issue

Steps to reproduce the issue

1. run a container with network mode host or none (podman run --network=host alpine sleep 1000)
2. check the container's network settings (podman inspect $id)

Additional information

This is required for full docker compatibility, to make the testcontainers-java test suite pass, see testcontainers/testcontainers-java#6158

I'm not sure how big the scope of the required changes for this is, but I'd be happy to contribute a fix if someone can point me in the right direction.
